初识python之画图神器篇

初识python之画图神器篇

前言

前面我们写了一篇关于python实例的汇率转换的文章，有的小伙伴说它虽然可以解决我们生活中的实际问题，但是好像缺少点什么。

我仔细想了想，想起了一句话，“生活不止眼前的苟且，还有诗和远方！”，确实我们应该用python来解决和丰富我们的生活。那么这期文章我就为大家介绍关于python的艺术美——画图神器

在数学中有一种美，叫几何美，我们又称为艺术美，用具有规律的线条，迭代出美丽的图片，这就是许多艺术家在创作是的灵感渠道。下面我们就为大家准备了一个简单的五角星绘制。

****涉及第三库的导入，模块的导入，还有一些我想我现在也介绍不完，下面就让我们一起来领略美感吧！

import turtledef draw_recursive_pentargram(size): ''' 迭代绘制五角星 ''' count = 1 while count <= 5: turtle.backward(size) turtle.right(144) count += 1 # 五角星绘制完成，更新参数 size += 10 if size <= 100: draw_recursive_pentargram(size)def main(): ''' 主函数 ''' turtle.speed(0) # turtle.penup() turtle.forward(40) # turtle.pendown() turtle.pensize(2) turtle.pencolor("red") turtle.bgcolor('black') size = 50 draw_recursive_pentargram(size) turtle.exitonclick()if __name__ == "__main__": main()

看似复杂而又繁琐的代码，它其实是由规律的，不信你可以自己看看它的写法。
